"""Phase 4 tests for CaidoCapability.

The capability has three observable behaviors that need parity with the
PLAYBOOK contract:

1. ``process_manifest`` injects http_proxy / https_proxy / ALL_PROXY env
   vars into the manifest's ``Environment.value`` dict.
2. ``tools()`` returns the seven Caido SDK function tools we wrapped in
   Phase 2.5 — same instances, in the documented order.
3. ``bind`` schedules an aggregated healthcheck task; the orchestration
   hook later awaits it on first agent start.

The healthcheck task itself is exercised by the healthcheck unit tests;
here we only verify the wiring (task created, name set, points at the
right ports).
